Simulation in the Wakefield Frame (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption A simulation of the same system in the boosted frame of the wake, moving at near lightspeed. Space has contracted, so that the laser wavelengths and the buckets in the wake have similar proportions. Time has stretched, so that first the laser interacts with the plasma, then the buckets are formed one at a time, and finally the electron beam is accelerated. Because of the separation of events in time, the laser has already left the plasma (in yellow rectangle) when the bucket accelerates the beam. Relatively few time steps are needed to model the events, which means less computer time.
